量子通信中的密钥设计是整个量子通信系统安全性的重要保障，传统的密钥设计方法采用固定密钥，无法实现变密钥加密，所以密钥和通信内容被破解的概率很高。提出一种基于色散评价的量子通信变密钥混沌加密实现方法，每次通信时，从混沌学的角度提取所有待通信数据的深层次特征，然后形成本次通信的加密和解密密钥，随通信内容的不同，系统密钥实时变化，在接收端，通过密钥和通信内容的混沌匹配来实现解密，并采用色散特性对加密效果进行评价。通过一组通信内容进行混沌加密性能测试，结果显示，基于色散特性衡量下的混沌加密特性安全性较传统方法大大提高，加密文本被破解的概率是0.0011%。

The key of quantum correspondence was the most important thing for quantum correspondence system security. A realization of chaotic valid encryption keys in quantum correspondence based on evaluation of dispersion was proposed, in each correspondence, the key was generated from the extraction of all correspondence data with chaos method, with the different correspondence contents, the system key changed in real time, at the receiving node, the content of the correspon-dence and the key was matched to achieve chaotic decryption and the evaluation of dispersion was used to evaluate the per-formance of chaotic encryption. A team of correspondence content was used to test the performance of chaotic encryption, the result shows that with the chaotic encryption key, the performance of the security was greatly improved, and the proba-bility of encrypted cracked is 0.0011%.
